First attempt at making a PC board with the GF

Here’s a look at the GF resist (er, spray paint) removal results. Speed 500, full power, 600+ lpi.

Will update after ferric chloride etching! :slight_smile:


Neato! :grinning:


so when you dunk it in the ferric cloride the copper traces go away? of does it react with the spray paint? I haven’t made a PCB before, but it is certainly on my todo list, to create our halloween decorations.

Yes, the ferric chloride removes the exposed copper. You then wash off the resist to expose the copper underneath.

That’s what I thought, but always better to double check, and get it right. :slight_smile:

Ok! After allowing the ferric chloride to warm up before etching (it was chilly in the garage where I had it stashed), etching went fairly well!

Now I’m curious about how fine I might be able to go. This is just a power distribution board, so fine traces weren’t necessary.


Wow, that’s pretty cool application for the GF! I’ll have to give it a try in the not-too-distant future…

Yah. It really does not work cold.
